摘要

Improvements in cement production and prediction of cements' performance properties requires the application of material science which, in turn, requires the ability to determine and describe their micro- and macrostructures. Improved methods for determining the phase composition of cements using X-ray powder diffraction will facilitate this understanding. This project, part of the Partnership for High-Performance Concrete Technology at the National Institute of Standards and Technology (NIST), involves the development and testing of analytical methods necessary for characterization of cements. Rietveld refinements to model the complex X-ray powder diffraction (XRD) patterns of cementitious materials will provide phase, chemical, and structural information to more completely characterize them, and so provide an improved basis from which to investigate relationships between cement properties and performance properties.
